The residents and members of the group D.C. Vote were visiting the offices of members of Congress on Monday. Group members were dropping off postcards from residents who support a bill that would give the city voting representation. D.C. has some 600,000 residents but only one delegate who doesn't vote on the floor in Congress.

The Senate passed a bill granting D.C. voting rights in February, but senators added a gun amendment that many residents don't like. The bill still hasn't been voted on in the House. The group hopes to get a bill passed without the gun amendment in that chamber.
